Title: Brake Power Compensation Clutch Device of Vehicle
Inventor: LEE GANG U
IPC: B60T13/46
Filed: 2000-12-14
Abstract: PURPOSE: A clutch device for compensating the brake vacuum force of a vehicle is provided to continuously supply the vacuum force to a brake shoe for a specific time even if an engine is stopped during a travel. CONSTITUTION: A vacuum pump(2) connected to an alternator(1) transmits the vacuum force to a master vacuum unit via a vacuum hose. The vacuum pump having a flywheel(5) connected to a driven shaft(6) is connected to a rotating shaft(8) of the alternator via a clutch bearing unit(7). Outer and inner cylindrical units of the clutch bearing unit are interconnected via a flat key. The outer cylindrical unit is integrally connected with the driven shaft whereon the flywheel is installed. The inner cylindrical unit is connected with the rotating shaft of the alternator via another flat key. If an engine is stopped during a travel, the vacuum pump is operated continuously by the rotation of the inner and outer cylindrical units. A ball between inner and outer clutch cylinders moves to the deep portion of a trapezoid-shaped inclined slit. Thus, the rotational force of the outer clutch cylinder is not transmitted to the inner clutch cylinder. Therefore, the vacuum force is supplied to the master vacuum unit by operating the vacuum pump for a specific time.
